.PREV DISCUSSION... /issued 240 PM EDT Sun Jun 21 2020/

SHORT TERM /Tonight through Monday Night/...

Current radar loop shows showers and thunderstorms popping across
the area as an upper level shortwave moves east through the flow.
The main hazards continue to be being gusty winds, frequent
lightning, and periods of heavy rain with these storms. The storms
are expected to continue through the evening hours then diminish
tonight as we loose daytime heating. As this wave continues to push
NE tonight the better dynamics and instabilities associated with it
move further north as well.  There is still a slight chance these
showers will continue overnight through Monday morning, but any
storms that survive will be isolated in nature and mainly over N GA.
The overall southwesterly flow is expected to continue Monday and
Monday night and should advect additional moisture across the
southeastern states through the middle of the week. This will bring
additional perturbations across the area keeping precip chances
elevated through Wednesday.

With precip chances increasing through the week, Temperatures will
slowly fall from the Mid 80s to Mid 90s down into mainly the 80s to
near 90 by Wednesday. Overnight temperatures are forecast to stay
mainly in the 60s to lower 70s.

01

LONG TERM /Tuesday through Sunday/...

First portion of the long term looks to be the most active
convectively as models are in good agreement with broad upper trough
NW of the region allowing for persistent SW mean fetch off the Gulf
and resultant ample moisture advection. GFS has high PWATs in 1.5-2
inch range Tues/Wed so will need to watch for isolated flash
flooding threat with any stronger storms. Main moisture axis should
shift southward across the area with a frontal passage later Wed
into Thurs, then models have discrepancies on how far south the
boundary/moisture field advects and how much weak ridging sets up
into the end of the week. While kept higher chance pops to mainly
central GA for Thurs, there's enough diurnal forcing and available
energy to have continued chance pops returning to other portions
of the area by Friday into the weekend despite any ridging.

Temps look to be below normal Tues thru Thurs then rebound back to
near normal Friday into the weekend.

.AVIATION...
00Z UPDATE...

Main line of TSRA has pushed past the ATL area terminals and look
to remain just south of AHN. Will need to carry a short term TEMPO
for both CSG and MCN. Otherwise, could be some reductions to VSBY
given the abundant rainfall but guidance indicates most should
remain north of the TAF sites. A repeat performance for Mon
likely in store with just perhaps and slightly later start. Will
carry Prob30 for all sites starting between 19Z and 20Z. Winds to
remain from the west side and less than 10 kts.

//ATL CONFIDENCE...00Z UPDATE...

High on all elements.
